Setting a webview delegate for a segue controller? - ios

Question

I have two view controllers connected by a modal segue. The destination controller also has a UIWebView.
Reading the docs I would like to elect the first controller to be responsible for dismissing the webview controller and my action for doing so would be in a webview delegate method.
I'm trying this:
First controller:
#interface ABISignInViewController : UIViewController <UIWebViewDelegate>
...
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
...
} else if ([[segue identifier] isEqualToString:#"showWebViewForSignUp"]) {
ABIWebBrowserViewController *webViewController = (ABIWebBrowserViewController *)segue.destinationViewController;
[webViewController.webView setDelegate:self];
[webViewController setUrlString:#"https://myurl"];
}
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSLog(#"%#", request);
return YES;
}
The second controller fires up and start loading the requested url:
- (void)viewDidAppear:(BOOL)animated {
NSURL *url = [NSURL URLWithString:self.urlString];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
}
However the delegate method in the first controller is never called.
Any directions?

Answer 1

Why not pass the URL as an NSString or an NSURL and then let the ViewController with the WebView handle the delegate methods?
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
...
} else if ([[segue identifier] isEqualToString:#"showWebViewForSignUp"]) {
ABIWebBrowserViewController *webViewController = (ABIWebBrowserViewController *)segue.destinationViewController;
webViewController.urlString = #"https://myurl";
}
}
WebView ViewController:
- (void)viewDidAppear:(BOOL)animated {
NSURL *url = [NSURL URLWithString:self.urlString];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSLog(#"%#", request);
return YES;
}
